Court documents have revealed that Murad Dervish, who allegedly shot and killed University of Arizona professor Thomas Meixner on Wednesday, had been expelled and banned from campus after several reports of him threatening staff. Dervish, 46, was expelled in February and staffers were alerted to call the police if he entered the campus’ Harshbarger building. Several people called the police when they saw him enter the building on Wednesday, but he allegedly still managed to shoot and kill Meixner before driving off. After he was pulled over by police, he said, “I hope he’s OK. Probably wishful thinking,” according the court documents obtained by ABC15 Arizona. He also told police “a woman wouldn’t have done this” and that he “just felt so disrespected by that entire department.” Dervish faces a first-degree murder charge and is being held in the Pima County jail without bond.
